Young Modulus of a thin plate in the through-thickness direction



Sudook A. Kim, H M. Ledbetter


We give a new approach to obtain the through-thickness-direction along the Young modulus of a thin orthotropic plate. The method minimizes errors because eight of nine measurments are made along principal directions. To verify the method, we used a macroscopically orthotropic textured copper plate, which we measured also by acoustic-resonance spectroscopy. The proposed method also yields all off-diagonal elastic coefficients simultaneously and self-consistently.
